Hjc Rpha 31 Chelet Helmet Grey

The RPHA 31 offers enhanced shock resistance and maximum protection thanks to its Premium Integrated Matrix (PIM) Evo shell and multi-density EPS. Engineered for a quieter, more aerodynamic ride through extensive wind-tunnel testing, the sun-visor-equipped RPHA 31 decreases noise level and wind turbulence. The RPHA 31 will also accept the second generation of SMART HJC Bluetooth communication systems, allowing riders to stay connected and focused on the road ahead.

Meets or exceeds ECE 22.06 approved. Testing includes energy attenuation, penetration resistance, chin strap structural integrity and labeling requirements for on-road motorcycle helmets.

The RPHA 31 has an extended shell & chin EPS to provide full face level fitting compared to classic open-face helmets. It also comes along with a brand new visor deflector that you can pull out and a visor holder to reduce noise, secures the visor, and block the incoming wind. Tested in the laboratory as well as in “real life” to meet the highest quality standards, HJC is one of the very few helmet companies equipped with its own state-of-the-art wind tunnel laboratory to test aerodynamics, ventilation, noise, and more.

The SMART HJC 2ndgeneration premium Bluetooth communication system models implement an all-in-one design, that is fully integrated into the helmet, allowing you to feel the optimal weight balance and aerodynamic performance while riding. The SMART HJC 50B and 21B can be installed on RPHA 71, RPHA 91, RPHA 31, or i71. Co-developed with SENA and tailored specially for HJC helmets.
